Re: Multiple Conditional Statements

[sundialsvc4]

Anytime I see repeating-variable names like $RBn, I immediately think that $RB should instead be, say, a list with n elements in it.   And in this case, that maybe the root variable should be a hash with keys such as 'RB', 'TE', 'WR'.

When looking for dupes, and especially if the values are scalar or string, a hash can come in handy:   you jump-out as soon as anything exists(), viz ... for illustration only ...

my $dupes = {};
for my $k (qw/RB TE WR/) {
  for my $n (qw/1 2 3 4 5/) {
    $n = $my_data->{$k}{$v};
    return 'DUPLICATE FOUND' if exists($dupes->{$n});
    $dupes->{$n} = 1;  // DON'T CARE ANY VALUE WILL DO
  }
}
return 'NO DUPLICATES';

This example illustrates the use of a hash ($my_data) to store the values, and of a hash ($dupes) to find duplicates.   The technique would not work so-good if the values being sought were floating point.)
